Abstract: Automatic slitter rewinder machine which includes a plurality of pairs of core-holding frames for releasably mounting a core therebetween and for winding up on the cores slit narrow web sheets to full rolls and automatic delivery apparatus for cooperating with the pairs of core-holding frames after winding-up to conduct a series of automatic roll changing steps for the next winding. The pairs of core-holding frames are suspended to be slidably movable. The automatic delivery apparatus is disposed below the pairs of core-holding frames and has a roll delivery carriage including a wrapping device for cut trailing ends of unloaded full rolls, a carriage for transferring the full rolls outside the machine, a conveyor for carrying and discharging the rolls, and a lifter for the conveyor, the wrapping device having swing rollers capable of moving toward and away from each other so as to conduct the wrapping and to carry the full rolls onto the conveyor.

Abstract: A multi-spindle turret winder of surface winding--center winding system provided with a first contact roller partaking in initial winding from a first winding station to an intermediate station and a second contact roller partaking in, after change-over from the former, winding-up to roll products from the intermediate station to a second winding station.

Abstract: An end-trimming apparatus for roll-like products. The apparatus trims both ends of a roll comprising a sheet-like material wound up on a core, particularly, stretchable one such as plastics film, by cutting off the irregularity of both the ends, finishing them into flat faces. It comprises a conveying means for carrying rolls horizontally to a given location, a supporting means of a pair of chucks for supporting the roll at both the ends, while providing it with a rotation in the winding direction of the roll, and a cutting means provided close to the pair of chucks, including a pair of disk cutters arranged co-axially and having respectively separate shafts parallel with the shafts of the chucks, the disk cutters being capable of moving toward and away from each other and of reciprocating in the direction at right angle to said toward-and-away motion.

Abstract: A method and roll-winding apparatus for automatically winding into rolls a sheet of material and automatically applying a leader tape to the trailing end of a length of sheet material wound into a roll. The trailing end section may likewise be automatically reversely folded outwardly over itself to form a tab on the wound roll for easy removal of the sheet material on a wound roll. The apparatus carries out the method automatically with a continuously driven winding drum to which elongated cores are presented sequentially parallel thereto for driving of the cores individually and transversely of a path of travel of the longitudinally travelling sheet material to be wound as corresponding lengths on the cores individually. The leading end sections of the succeeding lengths of sheet material are automatically wound on individual cores.
